ZocDoc

ZocDoc uses the Web to make health care simpler and more efficient.

With ZocDoc, patients can book doctor and dentist appointments instantly, at any time, making the appointment process vastly easier and more convenient. Doctors can use ZocDoc to reach prospective patients and use their time more efficiently by filling open appointments, which often occupy up to 20% of even the busiest doctor’s calendar. ZocDoc was founded in April 2007 by serial entrepreneurs Cyrus Massoumi, Oliver Kharraz, MD, and Nick Ganju.
